For first 2–3 wk of nestling period, female present at nest about 90% of time, male present about 50% of time; at least 1 adult at nest almost 100% of time. Both sexes hunt and feed young. Adult brings food to nest, tears off small pieces, and delivers them to young at early age. Male provides most of food in first 2 wk, while female tends young in nest . After 3–4 wk, female delivers as much prey as male.   After 3–4 wk, young able to peck at food but not able to tear off food and feed self until 6 wk.  Male was tearing apart food and feeding chick during my observation time late afternoon.
